In [1]}, the author presents a CP decomposition of the tensor with rank 40 that contains ones, \(1/8\) 's and zeros in the factor matrices.
This solution can be converted through an appropriate De Groote transformation into another solution that contains only zeros, and plus or minus 1/2. It was converted through
the method proposed in [2]}, by numerically minimizing the L1 norm of the factor matrices via De Groote transformations.
